CDC.gov: Outbreak Update

NEW: The lines on the tabular situation reports, sent to WHO headquarters each day by its country office in Nigeria, have now been full of zeros for 42 days. On October 20, WHO officially declared Nigeria is now free of Ebola virus transmission.

- On the morning of October 14, a second healthcare worker at Texas Presbyterian Hospital who provided care for the index patient reported to the hospital with a low-grade fever and was isolated. The healthcare worker tested positive for Ebola according to preliminary tests.

- On October 10, a healthcare worker at Texas Presbyterian Hospital who provided care for the index patient reported a low-grade fever and was referred for testing. The healthcare worker tested positive for Ebola according to preliminary tests by the Texas Department of State Health Services’ laboratory. The healthcare worker was isolated after the initial report of a fever and remains so now. CDC confirms that the healthcare worker is positive for Ebola.

- CDC is implementing enhanced entry screening at five U.S. airports that receive over 94% of travelers from Guinea, Liberia, and Sierra Leone.

- A confirmed case of Ebola has been reported in Spain.

- On September 30, 2014, CDC confirmed the first travel-associated case of Ebola to be diagnosed in the United States. The patient passed away on October 8, 2014.

- New cases continue to be reported from Guinea, Liberia, and Sierra Leone.

- Nigeria and Senegal have not reported any new cases since September 5, 2014, and August 29, 2014, respectively. All contacts in both countries have now completed their 21-day follow up, with no further cases of Ebola reported.

- The Democratic Republic of the Congo (DRC) has reported cases of Ebola. These cases are not related to the ongoing outbreak of Ebola in West Africa. For information on the outbreak in DRC, see the 2014 Ebola Outbreak in DRC page.

Ebola Ecology

Did You Know ...

Ebola, previously known as Ebola hemorrhagic fever, is a rare and deadly disease caused by infection with one of the Ebola virus strains. Ebola can cause disease in humans and nonhuman primates (monkeys, gorillas, and chimpanzees).

Ebola is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. There are five identified Ebola virus species, four of which are known to cause disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), has caused disease in nonhuman primates, but not in humans.

Ebola viruses are found in several African countries. Ebola was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of the Congo. Since then, outbreaks have appeared sporadically in Africa.

The natural reservoir host of Ebola virus remains unknown. However, on the basis of evidence and the nature of similar viruses, researchers believe that the virus is animal-borne and that bats are the most likely reservoir. Four of the five virus strains occur in an animal host native to Africa.

About Ebola

Ebola Signs and Symptoms

Fever (greater than 38.6°C or 101.5°F)

Severe headache

Muscle pain

Weakness

Diarrhea

Vomiting

Abdominal (stomach) pain

Unexplained hemorrhage (bleeding or bruising)

Symptoms may appear anywhere from 2 to 21 days after exposure to Ebola, but the average is 8 to 10 days.
Recovery from Ebola depends on good supportive clinical care and the patient’s immune response. People who recover from Ebola infection develop antibodies that last for at least 10 years.

Risk of Exposure

Healthcare providers caring for Ebola patients and the family and friends in close contact with Ebola patients are at the highest risk of getting sick because they may come in contact with the blood or body fluids of sick patients. People also can become sick with Ebola after coming in contact with infected wildlife. For example, in Africa, Ebola may spread as a result of handling bushmeat (wild animals hunted for food) and contact with infected bats. The virus also can be spread through contact with objects (like clothes, bedding, needles, syringes/sharps or medical equipment) that have been contaminated with the virus or with infected animals.
